JOGL - Installation


Advertisements


This chapter covers setting up of the environment to use JOGL on your system using different Integrated Development Environments (IDEs).

Installing JOGL

For JOGL Installation, you need to have following system requirements −

System Requirements

The first requirement is to have the Java Development Kit (JDK) installed on your machine.

Requirement Description
JDK Version 1.4 or above
Memory no minimum requirement
Disk Space no minimum requirement
Operating System no minimum requirement

You need to follow the given steps to setup your environment to start with JOGL application development −

Step 1 - Verifying Java Installation on Your Machine

Open console of your system and execute the following java command −

Platform TASK COMMAND
Windows Open Command Console C:\>java-version
Linux Open Command terminal $ java -version
MAC Open Terminal Machine:~ joseph$ java -version

Verify the output on the respective operating system.

Platform Output
Windows

Java “1.6.0.21”

java(TM) SE Runtime Environment(build 1..6.0_21-b07)Java HotSpot(TM) Client VM(build 17.0-b7, mixed mode, sharing)

Linux

Java “1.6.0.21”

java(TM) SE Runtime Environment(build 1..6.0_21-b07)Java HotSpot(TM) Client VM(build 17.0-b7, mixed mode, sharing)

MAC

Java “1.6.0.21”

java(TM) SE Runtime Environment(build 1..6.0_21-b07)Java HotSpot(TM) Client VM(build 17.0-b7, mixed mode, sharing)

Step 2 – Setting up Java Development Kit (JDK)

If Java is not installed on your machine, then you need to install Java SDK from the Oracle website: Oracle. You can find instructions for installing the JDK from the downloaded files. You need to follow the given instructions to install and configure the setup. Finally, set PATH and JAVA_HOME environment variables to refer to the directory that contains java.exe and javac.exe files, typically java_install_dir/bin and java_install_dir respectively.

Set Java-home environment variable to point to the base directory location on the same path, where Java is installed on your machine.

Platform Command
Windows Set the environment variable JAVA_HOME to C:\ProgramFiles\Java\Jdk1.6.0_21
Linux Export JAVA_HOME=/usr/local/java-current
MAC Export JAVA_HOME=/Library/Java/Home

Append Java compiler location to System Path as follows −

Platform Command
Windows Append the string ;%JAVA_HOME% bin at the end of the system variable and path
Linux Export PATH=$PATH:$JAVA_HOME/bin/
MAC Not required

Step 3 – Downloading JOGL

  • You can download latest version of JOGL from the website www.jogamp.org

  • Go to the home page of www.jogamp.org

  • Click on Builds/Downloads > Current (zip).

Jogamp Home Page

This takes you to the list of .jar files for all APIs maintained by the website.

JAR Files List
  • Download the library .jar file jogamp-all-platforms.7z, java documentations for OpenGL native library glugen-javadoc.7z, and JOGL jogl-javadocs.7z.

  • Extract the downloaded .jar files using any zip extracting software.

When you open the extracted folder, you will find jar folder, source-codes, and other files.

Source Code Folder

Get the source codes gluegen-java-src.zip and jogl-java-src.zip for supporting IDE. This is optional.

  • Inside the jar folder, there are multiple .jar files. This collection of files belongs to Glugen and JOGL.

  • JOAMP provides native libraries that support various operating systems such as Windows, Solaris, Linux and Android. Hence, you need to take appropriate jar files which can execute on your desired platform. For example, if you are using Windows 64-bit operating system, then get the following .jar files from the jar folder −

    • gluegenrt.jar
    • jogl-all.jar
    • gluegen-rt-natives-windows-amd64.jar
    • jogl-all-natives-windowsamd64.jar
JAR Files

Setting up JOGL for Eclipse 4.4

Follow the given procedure for setting up JOGL −

Adding Libraries

Step 1 − Open Eclipse.

Step 2 − Create a new project.

Step 3 − Create a new folder named lib in the project folder.

Step 4 − Copy the files gluegen-rt-natives-windows-amd64.jar, gluegenrt.jar, jogl-all-natives-windowsamd64.jar and jogl-all.jar into the lib folder.

Eclipse1

Step 5 − Now select these files and right click your mouse button. A shortcut menu is displayed, which contains Build Path > Add to Build Path.

Eclipse2

Step 6 − To make all .jar files available to other projects, go to main menu. Select Window > Preferences. The Preferences window appears.

Eclipse3 Eclipse4
  • In preferences window, in the drop down menu on the left hand side, follow the hierarchy- Java → Build Path → User Libraries.

  • Click on “New…” button.

  • It opens up a dialog box. Enter the library name as jogl2.1.

  • Add jar files glugen-rt.jar and jogl-all.jar using button “Add External JARs...”.

  • It creates a new user library named jogl2.1.

In the same way, we can add java documentation and source code for the added.jar files.

Adding Native Libraries

Step 1 − Expand the jogl-all.jar node, select Javadoc location (none).

Step 2 − Click on “New…” button. Enter the name for JOGL Java Document.

Step 3 − Click on “Add External JARs…” button.

Step 4 − It opens a dialog box where you need to select the location of JOGL Java documentation, which we already have downloaded earlier.

Adding source code

Step 1 − Select the node Native library location: (None).

Step 2 − Click on “New…” button.

Step 3 − Enter name for native libraries and click “OK” button.

Step 4 − Click on “Add External JARs…” button.

Step 5 − Now select the path where native library files ('gluegen-rt-natives-windows-amd64.jar and joglall-natives-windows-amd64.jar') are located.

Step 6 − Repeat the same procedure for source code.

Step 7 − We can set the locations for Javadoc, source code and jar files in the same way as given above for both native library files glegen-rt.jar and glugen-natives-windows-amd64.jar.

Step 4 − Browse for the path that contains JOGL native libraries gluegen-rtnatives-windows-amd64.jar'' and 'jogl-all-natives-windowsamd64.jar.

Adding Java Documentation of Native Libraries

You need to open Ant library manager again to make sources and Javadoc available for each project. Follow the given procedure −

Step 1 − Open main menu.

Step 2 − Select Tools > Libraries. This leads you to Library manager.

Step 3 − Under the JavaDoc tab, click on “New Library…” button.
